<p>PROBLEM TO BE SOLVED: To provide a by-product gas recovery method, a by-product gas use method, and by-product gas recovery equipment, by which a by-product gas can be efficiently utilized.SOLUTION: A by-product gas generated in an ironworks is compressed, and the compressed by-product gas is stored in a gas holder. The by-product gas can be stored in the gas holder by using, for example, by-product gas recovery equipment having: a compressor for discharging condensed water generated in compression operation to the outside while compressing the by-product gas which is generated in the ironworks; and the gas holder for storing the by-product gas which is supplied from the compressor. Here, it is preferable that the by-product gas recovery equipment comprises an electric generator which generates power by utilizing energy generated in the decompression operation of the by-product gas which is supplied from the gas holder.</p> |
